A little while back someone posted a question concerning arrow points and bow types from the interior of British Columbia Canada. Well, I can't find the thread but here are some photos of arrowheads from that area. The small black side-notched points are true arrowheads. The one with multiple side notches is called a "Clan" point locally.
